Email is blurring work lines

A new study has found that on average people start checking their emails at 7.42am and don't stop until almost 12 hours later, at 7.19pm.

The survey of 1000 European and United States workers and bosses by Seattle technology company Mozy said the advent of smartphones and cloud computing meant workers were always in touch with the office.

And it found three-quarters of bosses don't mind employees being half an hour late because they are confident they will have been working elsewhere.
